Weekly Salary [Edabit]

Write a function that takes a list of hours and returns the total weekly salary.

• The input list hours is listed sequentially, ordered from Monday to Sunday.
• A worker earns $10 an hour for the first 8 hours.
• For every overtime hour, he earns $15.
• On weekends, the employer pays double the usual rate, regardless how many hours were worked previously that week. For instance, 10 hours worked on a weekday would pay 80+30 = $110, but on a weekend it would pay 160+60 = $220.

Examples

weeklySalary([8, 8, 8, 8, 8, 0, 0]) ➞ 400

weeklySalary([10, 10, 10, 0, 8, 0, 0]) ➞ 410

weeklySalary([0, 0, 0, 0, 0, 12, 0]) ➞ 280

Notes

Every element in the array is greater than or equal to 0.

function weeklySalary(hours) {
  let salary = 0;
  for (let i = 0; i < hours.length; i++) {
    if (i < 5) {
      if (hours[i] > 8) {
        salary += 8 * 10 + (hours[i] - 8) * 15;
      } else {
        salary += hours[i] * 10;
      }
    } else {
      if (hours[i] > 8) {
        salary += 8 * 20 + (hours[i] - 8) * 30;
      } else {
        salary += hours[i] * 20;
      }
    }
  }
  return salary;
}
